This plant is considered weedy and invasive, but it is also pretty and edible. I ripped most of it out of my garden, but I learned that it is good for butterflies, so I will let my remaining plant spread again. This was taken on a garden tour today in Stony Creek, CT
Very pretty shot. I've been seeing it everywhere around here while it is in bloom. I pulled it from my yard because it's non-native, as you know. Hard to know what to do.
